  • A major challenge in clinical periodontics is to find a reliable molecular marker of periodontal support loss with high sensitivity, specificity and utility (Buduneli & Kinane 2011). Molecules derived from inflamed host tissue and pathogenic bacteria have the potential of being used as markers of periodontitis; however, molecular markers of bone resorption have advantages as they relate to specificity for bone, easy detection, pre-analytic stability and availability of sensitive and specific assays for detection (Forde et al. 2006).

  • For the earthquake motion level 1, the elastic limit the value of a structure is usually adopted seismic activity. For Level 2 earthquake motion, on the other hand, the limit value that a structure does not collapse or repair through the seismic activity depends on the importance of intended structure. Level 2 earthquake motions are used for verification is based on the records of strong motion seismograms obtained from the Hyogoken Nanbu earthquake and the other, and seismic waveform types are assigned according to the ground....

  • This book pilots the reader into the future. The first three chapters introduce new materials and material processing methods. Then five chapters present innovative new design directions and solutions. The main section of the book contains ten chapters organized around problems and methods of manufacturing and technology, from cutting process optimisation through maintenance and control to the Digital Factory. The last two chapters deal with information and energy, as the foundations of a prospering economy....

  • Synthetic polymers are essential for modern human life, since they are used in industrial and agricultural fields. However, most synthetic polymers that have been developed by using petroleum and coal as raw materials are not compatible with the environment, since they cannot be included in the natural recycling system. There are serious contradictions between the convenience that people require today and compatibility with the natural environment. It is easy to say that we should use only natural materials in order to solve the problems coming from man-made materials.

  • According to the Intergovernmental Panel on Climate Change, the impacts of climate chang on the water cycle are already evident and projected to increase substantially in the futur Climate change impacts the quantity and qua of freshwater resources and the frequency of extreme events, such as floods and droughts While climate change is only one of many drivers increasing pressure on water resource its impact is projected to be significant and to accelerate over time. Climate change reinforc and adds urgency to the case for good water resources management more generally.

  • In theory, significant percentage of energy that can be used for human needs, before it is allowed to complete cycle of energy flow (that is to be dissipated to space). Some of it may be exploitation and use as a solar energy directly, but another way to use natural photosynthesis to create biomass can be viewed as a form of chemically stored solar energy energy.

  • In order to evaluate the status of damage caused by the stresses on the plants growing process before visible damage is noticed, we have followed the evolution of the Chl content in the plant leaves using the Fr/FFr chlorophyll fluorescence ratio. The absolute emission signal of leaves can vary from sample to sample due to small differences such as excitation and sensing angles of the fluorescence, and the roughness and scattering properties of the leaf surface. Thus, the absolute fluorescence usually varies to a large extent than the fluorescence ratio.

  • Several of the conference’s participants presented the results of fMRI studies of participants performing aesthetic appreciation tasks. As in other areas of neuroscience, however, blobs of signifi- cant BOLD response tell us little unless one really understands their relation to the cognitive and affective processes involved in the specific task.

  • Two approaches were selected for the study, both of which were based on an initial hot water treatment: the “chemical” where bleached pulp is produced for printing and writing papers by hot water treatment and the following alkaline peroxide bleaching (Paper II–IV) and the “mechanical” where the unbleached material from the hot water treatment stage is mechanically refined (Paper II, V) to produce fibres for packaging grade papers. In the future, the straw fibre could be considered as a raw material for biocomposites.

  • Laboratory tables function as student workstations. School classrooms and science laboratories must provide each student with a workstation. Laboratory tables can accommodate 2–4 student workstations per table. The purchase of laboratory tables is a major expense for a school districts; therefore, tables should be well-constructed and maintained to support optimal student performance in the laboratory. The Scientific Equipment and Furniture Association (SEFA) has developed a list of performance properties for laboratory tables work surfaces. These properties are shown in Table 3.
